I propose to rename the tag dynamic (currently 8 questions) to dynamic-algorithms (currently nonexistent), because the questions with the tag are really about dynamic algorithms, that is, algorithms about certain objects with online updates.
(There was one closed question where the tag dynamic was used to mean dynamic programming. I modified this tag manually.)
I cannot use the existing system for creating a tag synonym (which would automatically merge the created tag synonym to the real tag) because the tag dynamic-algorithms does not exist at this moment. Therefore, I would like to invoke the official interim procedure for doing retagging for this purpose. This means:
Score +4 or more of this meta post is interpreted as a consensus that the tag dynamic should be renamed to dynamic-algorithms.
I do not think that the old tag dynamic should be a tag synonym after renaming, but I do not have a strong opinion about this.
